However, I get my School of divination wizard to cast suggestion on you again! This time, he replaces your save with his other portent roll, a 2.
The wizard hands me the sandwich, and I shake the platypus/cat saliva off of it.
Nerdy patches into the radio channel. "We're launching Project Apple Turnover. It's a mission to boost our recruitment. Can you send me some hemalurgic pies?"
Nerdy wonders how Platypus took the sandwich while shaking hands. Concluding that platypus must be an excellent pickpocket, Nerdy gets a school of divination wizard to come in and cast suggestion on Platypus to make him hand over the sandwich. Because School of Divination is ludicrously unbalanced, the wizard uses their portent feature to replace Platypus's saving throw with a nat 1.
Nerdy points out that a subjective set of values hardly makes for a fair and reasonable definition of cheating, then palms the sandwich while nobody is looking.
